    copied!<p>Below is a test I have knocked up that uses its own matcher. I know in this case I could use a standard matcher but in my real code I need a more complicated one.</p> <p>The test passes - tick VG. The issue is that there appears to be an extra call to <code>IArgumentMatcher.matches()</code> method that returns false, and yet the test passes.</p> <p>The output I get is:</p> <pre><code>30-09-2009 16:12:23 [main] ERROR - MATCH - expected[aa], actual[aa] 30-09-2009 16:12:23 [main] ERROR - MISMATCH - expected[aa], actual[bb] 30-09-2009 16:12:23 [main] ERROR - MATCH - expected[bb], actual[bb] </code></pre> <p>So the question is why am I getting the MISMATCH line, and have I done something incorrectly?</p> <p>The test code is:</p> <pre><code>package uk.co.foo; import static org.easymock.EasyMock.createMock; import static org.easymock.EasyMock.expect; import static org.easymock.EasyMock.replay; import static org.easymock.EasyMock.reset; import static org.easymock.EasyMock.verify; import junit.framework.TestCase; import org.apache.log4j.Logger; import org.easymock.EasyMock; import org.easymock.IArgumentMatcher; /** * */ public class BillTest extends TestCase { private static Logger mLogger = Logger.getLogger(BillTest.class); private BillInterface mMockBill; public void testTwoCalls() throws Exception { BillsTestClass sut = new BillsTestClass(); sut.setDao(mMockBill); expect(mMockBill.method1(eqBillMatcher("aa"))).andReturn(""); expect(mMockBill.method1(eqBillMatcher("bb"))).andReturn(""); replay(mMockBill); //test method sut.doSomething("aa"); sut.doSomething("bb"); verify(mMockBill); } public String eqBillMatcher(String aIn) { EasyMock.reportMatcher(new BillMatcher(aIn)); return null; } @Override protected void setUp() throws Exception { super.setUp(); mMockBill = createMock(BillInterface.class); } @Override protected void tearDown() throws Exception { super.tearDown(); reset(mMockBill); } public class BillsTestClass { private BillInterface mDao; public void setDao(BillInterface aDao) { mDao = aDao; } public void doSomething(String aValue) { mDao.method1(aValue); } } public interface BillInterface { String method1(String aValue); } public class BillMatcher implements IArgumentMatcher { private String mExpected; public BillMatcher(String aExpected) { mExpected = aExpected; } /** * @see org.easymock.IArgumentMatcher#matches(java.lang.Object) * {@inheritDoc} */ public boolean matches(Object aActual) { if (aActual.equals(mExpected)) { mLogger.error("MATCH - expected[" + mExpected + "], actual[" + aActual + "]"); return true; } mLogger.error("MISMATCH - expected[" + mExpected + "], actual[" + aActual + "]"); return false; } /** * @see org.easymock.IArgumentMatcher#appendTo(java.lang.StringBuffer) * {@inheritDoc} */ public void appendTo(StringBuffer aBuffer) { aBuffer.append("boo("); } } } </code></pre>
